Looking to make custom dialogue for a NPC merchant. Any tutorials, advice welcome. I've been browsing the dialogue for merchants in CK but it all is bundled together with all the dialogue from all the NPCs in the town or city.

I was going to suggest this page from the wiki, but it doesn't look like it has much on dialogue...

It seems the basic Merchant Dialogue is automatic, but there's nothing particular on dialogue on that page.

I'd wonder...

Can you search for that line "What have you got for sale?" and check any Scripts attached to it? I'd assume that it's just something like "OpenBarterMenu()" or whatever the command is in Skyrim; once you found it, you could just use any dialogue tutorial to set-up your dialogue, and stick that command in the relevant line? Sorry it's not more help :/
